They better not end so soon, there is a TON of stories to tell that can last for a couple more seasons:Honestly I was trying to find my sources, and maybe what I came across is just wishful thinking. This upcoming season could actually be the last. Cartoon Network has a habit of canceling dope shyt and replacing it with nonsense.
*Steven's power growth and him learning to use his abilities
*Steven & Connie's relationship
*How Amythist joined the squad
*The Crystal Gems early interactions with each other and how they learned to get along
*More fusions
*More Lapis backstory
*Peridot's evolution
*Possible Bismuth, Ruby Eyeball and Jasper returns and if they join the Crystal Gems
*More backstory about the Diamond Authority
*Yellow Diamond's invasion of Earth
*How the Crystal Gems won the first invasion
*The Crystal Gems possibly visiting Homeworld
*How Rose shattered Pink Diamond
*More humans joining the Crystal Gems
*More crossover episodes... maybe a return of Uncle Grandpa
*More Greg and Rose backstory
*Steven learning more about his mother Rose
....and so much more. If Regular Show, Adventure Time and so many other shows can get 8 plus seasons then Steven Universe deserves that as well. That plus a Steven Universe album needs to drop featuring every song ever sanged on the show plus bonus songs from Estelle
